The bacteria is known as MRSA, or methicillan-resistant staphylococcus aureus. It's resistant to many first-line antibiotics as well as many second-tier antibiotics. It's been seen in hospital patients for years, but is now being seen outside the hospital.
The New England Journal of Medicine reports it's a growing problem and dozens of children have died nationwide due to MRSA.
The bacteria has been found in gyms and in community washrooms. It can be especially dangerous for the elderly, young kids or people with chronic diseases.
Experts say the spread of this superbug is probably due to overuse of antibiotics. They hope more appropriate use will lead to less antibiotic-resistant bacterial infections.
